i'o all whom t may concern:

Be it known that I, BENJAMIN F. CLINE, of In ianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Window-Sash Fastener; and I do hereby declare that the following is a full, clear,

andeXact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

The object of this inventionis to provide an improved means for conveniently and effectively fastening windows, so that proper ventilation may be obtained by raising `the window or lowering it, or both, and yet prevent the entrance of burglars.

A feature consists in providing on the upper sash a plate with bolt-receiving holes in it and on the lower sash a lock-controlled bolt with means for locking the bolt both in the holding position and in the unholding position.

The features of the invention will be understood from the accompanying drawings and the following description and claim.

In the drawings, Figure 1 is an inside elevation of a window with the lower sash raised and the upper sash lowered and a lock in position, intermediate parts being horizontally broken away. Fig. 2is a perspective view of the fastener for securing the two sashes together. Fig. 3 is ahorizontal section through the same above the bolt in reverse direction to Fi 2. Fig. 4 is a vertical section through said astener on the line of the bolt and the adjacent parts of the sashes, showing them fastened. Fig. 5 is a view similar to that shown in Fig. 3, excepting that the bolt is locked in an unengaging position in Fig. 5, while it is in its outer position in Fig. 3.

In the different figures, represents the window-casing, 11 the upper sash, and 12 the lower sash.

14 is a fastener for lockin T thesashes relatively together, and 15 the fastener for locking-the lower sash with the window-Casin I secure the fastener 14 u lower sash at one side an adjacent the side of the upper sash. This fastener consists of an external casing with laterally-extending flanges 16, provided with screw-holes for securing the same to the sash, and also a downwardly-extending flan e 17 for securing it to the outer surface of t e lower sash. Since the side and bottom of the upper sash will on the top of thel always extend below and against this flange 17, no person outside the window can have access to the flange 17, so as to remove the screws. Within the casing I providea horizontally-moving bolt 18, that is guided in suitable apertures in the walls of the casing. It is pressed outward into engagement by the helical spring 19, one end of which rests against the wall of the casing and around the lug 20 and the other end of which bears against the extension 21 from the bolt and surrounds the lug 22. The inner end of the bolt 21 is corrugated or roughened and the casing at 23 recessed to enable one by h1s fingers to withdraw the bolt from locking engagement.

The bolt is locked in or out of position by a key-shaft 24, mounted in the bearings 25 of the casing and actuated by the removable key 26 and having secured to it a lockingfinger 27, that when the shaft is partly rotated moves into engagement with the extension 21 from the bolt 18 between the two flanges 28 from said extension, as seen in Figs. 3 and 5. When the finger 27 is between said flanges, the bolt is held in a locking position.. When the bolt is withdrawn to an unlocking position, the `hnger 27 may be moved in behind the extension 21 and one of the flanges 28, as seen in Fig. 5, and thereby the bolt will be locked in a disengaging position, so that the sashes may be moved up or down freely.

On the adjacent side of the upper sash a bolt-receiving plate 30 is secured that is pro vided at intervalswith bolt-receiving holes 31, adapted to receive the bolt 18. This plate 30 is preferably chambered, so that its surface stands some distance away from the surface of the upper sash, and thus holds the bolt without the need of making holes in the sash opposite the holes in the plate. This feature appears in Fig. 4.

With the foregoing fastener alone the sashes may be secured together, so as to surround the opening at the bottom or top of the window, or at both places; but said openings combined cannot exceed six or seven inches, for if so both sashes could be shoved up and the lower opening would be so large as to admit a person.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination with the overlapping sashes of a window, of a fastener secured to IOO the lower sash, a spring-actuated bolt in said fastener With a radial extension therefrom, a key-shaft parallel With said bolt, a linger on the upper sash of Jshe Window.

In Witness whereof l have hereunto allXed my signature in the presence of jche Witnesses herein named. v
